Create 3D model that have different cross sections

leo_morales — Wed, 24 May 2023 17:19:56 GMT

Hi, I would like to know if there are options in ArchiCAD that will let me create a 3D model with 2 different sections on both ends. Using morph is one, but if there are many points on both the sections, it will take time. Will use this in our project for excavation, in between stations, there are different cross sections. I attached a sample of what I would like to do. Both ends are created using morph. And when a 3D is made, it should look like the picture. Thanks.

If you have the shape of the two ends, then a ruled shell with detailed construction method and a 0 (zero) thickness will give you the joining sides.
It will be a hollow shell but you could always convert it to a morph ans make it solid.

That is great Mr. Barry, will try this once I start working on that. Thank you very much.

Another option, is to Select both Morphs > Right Click > Boolean Operations > Union.
Now both of your Morphs are part of a single geometry. Then you can draw custom edges between nodes by: Click one node of the Morph > Select the Pencil button > Draw your edge. Repeat as needed.
When you draw the last edge, you will see that the solid will be closed. Finally check the solidity by Selecting the Morph > Right Click > Check Solidity.
Hope this helps.

Thanks, I used this when the model is making a non-solid.
